Well I fashioned a tiny neck brace type thing for little stargazer, only left it on for half an hour then took it off, he had improved already and this morning is belting round the brooder like nothing was wrong. The last of the eggs have hatched, 13 out of 15, not bad and there is another stargazer, a bit worse than the first so it now has the little brace on, will leave this on for half an hour again and see if any improvement. Fingers Crossed!
